activiti-配置数据源为PostgreSql

 postgresql是数据库类型为postgres

在yml中配置activiti参数

spring:
   activiti:
      database-type: postgres # 数据库类型
      database-schema-update: true # 建表规则 为true会自动创建表
      db-history-used: false # 检测历史表是否存在

也可以在ActivitiConfig中直接配置

 /**
     * 流程配置，与spring整合采用SpringProcessEngineConfiguration这个实现
     * @param dataSource
     * @param transactionManager
     * @return
     */
    @Bean
    public ProcessEngineConfiguration processEngineConfiguration(DataSource dataSource, PlatformTransactionManager transactionManager){
        SpringProcessEngineConfiguration processEngineConfiguration = new SpringProcessEngineConfiguration();
        processEngineConfiguration.setDataSource(dataSource);
        processEngineConfiguration.setDatabaseSchemaUpdate("true");
        processEngineConfiguration.setDatabaseType("postgres");
        
        processEngineConfiguration.setTransactionManager(transactionManager);
        
        //流程图字体
        processEngineConfiguration.setActivityFontName("宋体");
        processEngineConfiguration.setAnnotationFontName("宋体");
        processEngineConfiguration.setLabelFontName("宋体");
        
        return processEngineConfiguration;
    }
